My ignition switch (repro) key is different than my door locks. I would like to keep my original door locks, so I was wondering if it is possible for a locksmith to recode them using just the ignition key.

*locksmith has to actually be a locksmith with training and then they can match the pins in the ignition tumbler to the same as the doors. Even easier if you have the original keys with the key code not knocked out. Or documentation with the key codes, but they can work from the key you have if it is not too worn.

67 also the Ignition and Doors should be the same. And the Trunk and Glove Box. My car has all the original Locks, and 1 set of original keys. There is a 4 digit code #L##, #=number L=letter. A good locksmith can cut you a set of keys from just the code. As has been stated, it has to do with the grooves, if the Ignition key will go into the Door locks (or vice versa) then yes they can be recoded to match. Also all of the locks and original keys have this 4 digit code stamped on them. I would recode the Ignition to match the Doors, that way you are only recoding 1 lock. If you recode the doors to match the Ignition, then you have to do 2. Just my 2c's.

Back in the 70's I took the cylinders from locks on my corvair to a local lock smith, and had him redo them. When I reinstalled them that afternoon, I had what I wanted. One key worked every lock and switch on the car. Kind of like they build them today. Wasn't real expensive, but some people thought it was stupid. I just wanted it simple.
